Certus’ silicon-proven I/O library in TSMC 180nm BCD provides a reliable and flexible solution for mixed-signal, power management, and BCD applications. The library includes a 1.8V digital I/O cell, optimized for up to 100MHz operation at 15pF, ensuring efficient high-speed performance. It also features 1.8V and 3.3V baseline analog I/Os, along with custom low-leakage 3.3V analog I/Os, tailored for low-power and precision-driven designs. Engineered for robustness, the I/Os meet 2kV HBM and 500V CDM ESD targets, providing strong protection against electrostatic events. With a balance of performance, power efficiency, and reliability, this I/O library enables seamless integration into demanding BCD and mixedsignal designs, making it an ideal choice for power management and analog-rich applications.
